having a tough time here.

[Mabyboi]

Im having an issue here with tubing. I have 1/2"ID and 3/4"OD primochill tubing, on 1/2" barbs. I have a TINY leak in my enzotech sapphire and need to take the tubing off... but im having SO much trouble with removing the tubing, its on REALLY REALLY REALLY tight. is there any specific way to take this off and make it easier? some trade secret i havent been told?

i cant just twist it off due to other connections.

thanks in advance!

use pliers to deform them..so you can pull them off

hmmm i see, but wont that ruin the tubing for the next time?

I generally find that if you rock the tube from side to side gently whilst pulling back, the tube will start making it's way up the barb quite easily.

Otherwise, get a hair drier and carefully try to heat up the tube ever so slightly at the barb, it should come off easily and it won't destroy it. Just don't keep it in there for long, you don't want to melt/burn anything, a couple of seconds is probably all it will take.

my bad...i don't re use tubes....i usually trim the used part...

GREEEAT NOW YOU TELL ME! lol i already pulled the tubes off with the pliers. worked quite well actually, gently rocked it back and forth. is all good...

anyone heard of the issue with the enzotech sapphire? small leak? gotta get a bigger o-ring. and re-paint it red... (sorry utnorris if you read this.. kinda scratched it lol)

[Hondacity]

just use clamps

[Mabyboi]

if i could get some of those koolance clamps. oh god i would looooooove that

I'm using 7/16'' ID tubing on 1/2 barbed fittings Previously I was using 1/2'' tubing on 1/2'' barbed fittings but I had some leak risks as far as I can saw. And during my last test for pumps... one of the tube pulled off the fitting (but I wasn't careful enough and did not use clamps, it was only for a test out of the pc case, have a look there on the tsunami: http://www.xtremesystems.org/forums/...43#post4157543 (last photo at the end of the page)

IMO using 7/16'' ID tube is more safe. It's not really harder to plug or remove this tubing on 1/2 barbed fittings. I succeed to plug 7/16'' masterkleer tubing on the stock D5 top ^^ Using hot water to relay the tube and ease the plugin process. You can also use the hairdryer, but not too hot.

The way I remove the tube from the fitting: I press the tube between my fingers 1 or 2 cm away from the fitting, then I make some small (very gentle, not too much to avoid breaking wb top or fitting sealing) movements left/right/left/right and with some patience and care, the tube is disconnected. Hope my english is good enough to explain what I mean

As you can see here, the tube is well compressed on the fitting, clamps are not really mandatory, you can use it to make sure but...I don't think it's usefull everywhere.



Cheers.

PS: some 7/16'' ID tubes I like to use: http://www.chilledpc.co.uk/shop/inde...ath=44_116_148 , the masterkleer is good but I prefer the Tygon R3603, or if black color is required the Primoflex Pro LRT.
For clamps, Koolance are ok but you can use these one http://www.chilledpc.co.uk/shop/index.php?cPath=72_165 the Primochill, very easy to use.

The Koolance clamps are great and they're so hard wearing. I'd say screw getting the screw ones and go for the Koolance quick-clips

Is it leaking where the tubing is over the barb or at the block where the barb screws in? If it is the latter I had the same issue and had to use a bigger o-ring. Also, I can't believe you scratched the paint.

[TJ TRICHEESE]

i would go for the koolance compression if i were you they work great and are easy to take off

[jinsean]

It's hard to believe that 1/2" ID tubing over 1/2" barbs would be hard to take off. I've been using 7/16" ID tubes over 1/2" barbs and now that's almost impossible to take off. I will attest to the fact that you wont have any leaks w/o using clamps when you do use 7/16" ID tubes over 1/2" barbs though. 2 years running leak free.

I decided to just go w/ compression fittings on my 3rd iteration of my WC loop. Hopefully, less hassle involved and no need to use boiling water to soften the tubing and such.

Use CLAMPS. At least bust out the zipties.

I used to be like you also, til i had a simular accident. After that i always have spare koolance clamps.


They dont look bad either.

Why somebody would not use clamps is beyond me...you would not do plumbing without using some sort of clamp at the end to prevent the hose from coming off the barb...why would you do it in the case of computer WC
